🔍 Key Concepts

• Speed-distance-time relationship: ( \text{Time} = \frac{\text{Distance}}{\text{Speed}} ) • Using the chart to measure the distance from your 1523 position to Shagwong Reef Buoy "7SR" • Converting decimal hours into hours and minutes

💭 Think About

• From the chart, how many nautical miles is it from LAT 41°08.2'N, LONG 71°34.4'W to Shagwong Reef Buoy "7SR" along your intended track? • Once you know the distance, what time in hours will it take to travel that distance at 8.7 knots, using ( \text{Time} = \frac{\text{Distance}}{\text{Speed}} )? • After you get the elapsed time in decimal hours, how do you convert the decimal fraction of an hour into minutes and then add it to 1523?

✅ Before You Answer

• Be sure your distance measurement is in nautical miles, not yards or statute miles • Double-check your speed unit is knots (nautical miles per hour) before using the formula • Confirm that when you add the elapsed time to 1523, you correctly handle any minute-to-hour carry (if minutes exceed 59)
